Lift Shaft and Staircase Ventilation – LSV
Staircase + Lift Shaft
Standard-compliant and energy-saving: The dual system LSV for smoke extraction and ventilation of lift shafts and stairwells in residential buildings.
The planning of buildings in conformity with standards places enormous demands on architects and specialist planners. In particular, it is necessary to implement the legal and normative requirements for ventilation and smoke removal. In this context, the former securing of the ventilation requirement through an external opening in the lift shaft head is in direct conflict with the airtight envelope of modern buildings. If the staircase and lift shaft are in one and the same fire compartment (building class 4), D+H has now developed the perfect solution to this problem with LSV: The Lift and Staircase Ventilation System (LSV) combines smoke and heat extraction with the mechanical ventilation of lift shafts.
In an LSV system, only one roof opening is required. With the use of an LSV, the parallel operation of a system for smoke and heat extraction in the stairwell and a system for smoke extraction and ventilation of a lift shaft can be avoided. The new, patented LSV solution from D+H thus reduces investment costs and saves energy costs in the long term.
A true plus for lift shaft and staircase ventilation
Solution components
Intelligent smoke extraction and ventilation
Our system for modern, airtight residential buildings is more than the sum of its comtonents!
LSV combines proven D+H drive and control technology with innovative product elements from BlueKit and purchased parts from selected partners.
-
The system is controlled by means of the compact CPS-B SHEV control panel from D+H with integrated emergency power supply. The LSVM active ventilation module controls the fan for mechanical ventilation of the lift shaft.
-
The air quality in the staircase is monitored by the D+H smoke detectors. A D+H operating button is used for status display. This also enables the manual SHEV alarm triggering, the smoke and heat extraction as well as the manual ventilation of the staircase.
-
A BlueKit status transmitter monitors the air quality and temperature at the overflow opening in the lift shaft. If necessary, this sends a signal to the system control for ventilation.
-
The fan mounted in the lower area of the shaft provides mechanical ventilation of the lift shaft. In the event of smoke development in the event of a fire, the fan switches off automatically.
-
If the system detects smoke in the staircase, the D+H rack and pinion drive in this example solution opens the skylight dome of the staircase, thus ensuring safe smoke and heat extraction.
BlueKit Technology
Trendsetting systems from the D+H Group
Lift constructors rely on BlueKit when it comes to ventilating lift shafts.
BlueKit systems and products for lift shaft smoke extraction have been convincing on the market for more than 10 years. The newly created system solution LSV of the D+H product brand BlueKit underlines the claim of the D+H Group to live its brand promise BUILDING ATMOSPHERE.
BlueKit systems permanently reduce building operating costs while ensuring maximum security. The idea behind it is as simple as it is clever: permanent openings in the lift shaft or stairwell remain closed and only open in the event of a fire. This saves heating costs. Closed shaft heads also increase building comfort at the same time: Unpleasant draughts inside are eliminated. The energy-efficient BlueKit systems are thus among the most modern shaft smoke extraction solutions in the world.
